PN STCE.J FOR DREDGE BUGKETS.

Application filed August G, 1921.

T 0 aZLZI'w zom 'it may concern Be it known that I, Mann L. Surnames, a citizen of the Uni-ted States, residing at Hammonton, in the county of Y uba and State of California, have invented certain new and useful improvements in Pin Stops tor Dredge Buckets, ci' which the following` is a speciiication. y

This invention relates to dredges, and more particularly to the means for securing the buckets in jointed or pivotal relation.

The general practice is to employ a pivot pin to connect the iront eyes ot one bucket to the rear eye of the next adjacent bucket, the pin carrying a lug which is riveted'in the lug-seat of the bucket. This practice is expensive and otherwise objectionable beA cause of the time lost in drillingy lic-les in the bucket and pin-lug to acccmmodate the rivet, and in heating and driving the rivet,

and sometimes in cutting out theY rivet whei'r it becomes necessary to remove the pin.

jectionable practice, and, .stated in generar terms, it embodies means termed integral with the bucket which prevents the pin from moving endwise and holds 'the lug securely in the seat.

Une embodiment or" the invention is shown in the annexed drawing, wherein-n Figure 1 is a sectional-elevational view ot a dredge bucket constructed in accordance with my invention; and

Fig. 2 is a plan view thereof, n

According to my invention, ,i cast the pinholding element integral with the bucket and preferably7 in the form of a semtcircular or segmental lug or overhang 5, ot 'which one is provided on the outside of each iront eye 6. rlhe lug 5 constitutes a stop to prevent endwise displacement ot the pin T and dispenses with the use ot rivets. The lug 8 et 'Specification of 'Letters latent.

the pin is accommodated in the slot or channel 9 and is retained therein by the segmental lug or overhang 5. In order to make possible the assemblage ot' the pins, the eyes are somewhat elongated as indicated. Since the overhang 5 also operates to confine the lug 8 to its seat 9, it is evident that there cannot'be suiicient lateral play oi the pivot pin to enable it to escape past the overhang. Moreover, there is always tension on the pins due to the weiglitof the buckets notwithstanding that the bucket line runs slack.

Having described my invention, I claim l. A dredge bucket having a pin opening` and a lug-seat, a pin for said opening and having a lug` adapted to said lug-seat, and means cast integral with the bucket to prevent endwise displacement of the pin and effective to conine the lug to its seat.

Q. si dredge bucket having a pin opening and a Iugseat, a pin for said opening and having a lug adapted to said lug-seat, and an element overhanging the pin opening to prevent endwise displacement ci the pin and eliective to confine the lug to its seat.

3. A dredge bucket whereof each front eye is formed with an overhang in line with the lug-seat, said overhang operating to prevent endwise displacement ci the pivot pin and confining the lug to its seat.

4. dredge bucket whereof each iront eye is termed with a segmental stop in line with the lug-seat, said stop operating to prevent endwise displacement ot' the pivot pin and conlining the lug to its seat and ensuring uniform wear on the pin and lug seat.

In testimony whereof I- atiiX my signa- MARK L. SUMMERS.
